武漢 合肥量子通信幹線建成貫通

Connecting Wuhan city of Central China's Hubei province and Hefei city of East China's Anhui province, a world-leading quantum Communication Line was officially put into service last Tuesday.

連接中國中部湖北省武漢市和中國東部安徽省合肥市的一條世界領先的量子通信線路，於上週二正式投入運營。

The Wuhan-Hefei trunk line is a major part of China's quantum communication network, designed to secure the information exchange in central China.

武漢-合肥幹線是中國量子通信網絡的重要組成部分，旨在確保華中地區的信息交換安全。

Thanks to the technology, users from the military, government, finance, and electricity sectors are able to send messages in a way that ensures only they and their intended audience can read them.

得益於這項技術，來自軍隊、政府、金融和電力部門的用戶能夠發送信息，確保只有他們和他們的目標受衆能夠閱讀這些信息。

The network, in comparison to traditional communication technologies, features ultra-high security and is able to ward off hackers by using quantum photons.

與傳統通信技術相比，該網絡具有超高的安全性，並能利用量子光子抵禦黑客。

China has made tremendous efforts in developing quantum technology over the years.

多年來，中國爲發展量子技術作出了巨大的努力。

In 2010, the first large-scale quantum communication test network in China began construction and started operation two years later.

2010年，中國第一個大規模量子通信測試網絡開始建設，並於兩年後投入運行。

In September 2017, the Chinese Academy of Sciences announced that the world's first quantum-encrypted network was ready for use, which connects Beijing and Shanghai, reaching further to Mozi satellite out in space. The total bandwidth of the ground network is about 20 kilobits per second.

2017年9月，中國科學院宣佈世界上第一個量子加密網絡即將投入使用，該網絡連接北京和上海，進一步延伸到太空中的墨子衛星。地面網絡的總帶寬約爲每秒20千比特。

One month later, the world's first quantum communication trunk line opened in China. Named "Shanghai-Hangzhou Quantum Communication Commercial Trunk Line (or Shanghai-Hangzhou trunk line)," the 260-kilometer-long connection links Shanghai Municipality and the eastern city of Hangzhou, with a price tag of nearly 25 million US dollars.

一個月後，世界上第一條量子通信中繼線在中國開通。這條名爲上海-杭州量子通信商業幹線（或稱滬杭幹線）的中繼線長260公里，連接上海市和東部城市杭州，標價近2500萬美元。
